Mono aminoethers of triphenyl ethylenes



United States Patent O i i MONO AMINOETHERS OF TRIPHENYL ETHYLENES N Drawing. Application September 5, 1957 Serial No. 682,073

6 Claims. (Cl. 260-2417) Our invention relates to new chemical compounds which may be regarded as derivatives of triphenylethanols, triphenylethylenes and tn'phenylethanes. They are distinguished, in general, by their anti-estrogenic activity in the endocrine system, anti-inflammatory activity, gonadotrophic activity and activity in decreasing blood cholesterol levels. Some of the compounds possess various combinations of these properties.

Asestrogen antagonists, the compounds are useful in the treatment of hyperestrogenism and disorders re lated to this condition, e.g., endometriosis, functional bleeding, Kleinfelters syndrome, dysmenorrhea, menopausal dysfunction, and similar conditions. They are active both orally and parenterally and so can be administered by either route, though the oral route is preferred in most instances. Some of the compounds have a high degree of activity as estrogen antagonists. Some of the compounds with anti-estrogenic activity are also uterotrophic.

As anti-inflammatory agents, the compounds are useful in alleviating the symptoms of such collagen diseases as arthritis and rheumatism and in the topical treatment of inflammation. Some of the compounds possess the novel combination of anti-inflammatory and anti-estrogenic activities and are especially advantageous for this reason.

As blood cholesterol depressants, the compounds are useful in the treatment of atherosclerosis. I As gonadotrophic inhibition agents, the compounds are useful for the treatment of fertility and sterility problems and can be administered orally or parenterally for this purpose.

The compounds can be used orally and parenterally in doses ranging between 25 mg. and 24 grams daily, depending on the condition under treatment. For topical use, the compounds can be incorporated into creams, ointments or lotions in concentrations of up to 10 percent. In aerosol sprays, the concentration can be in the order of about 0.05 to 1 percent.

The compounds can be isolated and are generally useful in the form of their salts with mineral acids, such as hydrochloric or hydrobromic acid or with organic acids such as citric, oxalic or the like. They can be used as the base, however.

. The compounds of our invention are derivatives of triphenylethanols, triphenylethylenes and triphenylethanes in which one of the phenyl groups is substituted by a basic ether group of the formula described below and in which the monophenyl substituted carbon atom in the ethanol, ethylene or ethane group is linked to one or two hydrogen atoms. The new compounds have the L 2 ,914,529 Patented Nov. 24,1959

. 2 in which X is an ethanol '(COHCH ethylene (C=CH) or ethane (CHCH group and in which one of the groups represented by R is a basic ether group of the formula OC,,H ,,A, wherein n is 2, 3 or 4 and A is a N-piperidino, N-morpholino, N-pyrrolidino or a 4- methyl-l-piperazino group. The group OC,,H ,,A is attached to a benzene ring by the oxygen atom in the para position to the point of attachment of the benzene ring to theethanol, ethylene or ethane group. The remaining R and R groups are hydrogen, halogen, methyl or methoxy.

The new ethanols can be prepared by reacting a substituted benzylmagnesium bromide or chloride with a benzophenone substituted with a OC,,H ,,A group. The benzophenone is obtained by reacting an alkali metal salt of a hydroxybenzophenone with a haloalkyl heter ocyclic such as chloroethyl piperidine. The ethanols can also be prepared by first preparing the corresponding ethanol containinga OC,,H ,,X group (where X is halogen) and reacting'this ethanol with a reagent prepared from a lithium alkyl. and a heterocyclic such as pyrrolidine. The ethanol containing the -OC,,H ,,X group can be prepared by reacting an alkali metal salt of a hydroxybenzophenone with an alkyl dihalide to form a benzophenone containing a OC,,H ,,X group followed by reaction with a substituted benzylmagnesium bromide or chloride. The new ethanols have the formula wherein R and R have the meanings described above.

The new ethanes are prepared by hydrogenation of the above ethylenes. The new ethanes have the formula OHOIEEQ wherein R and R have the meanings described above.

The compounds of our invention will be further illustrated by reference to the following examples.
